....one guild mate tells another in chat, for that milestone. Does he get a card from playa games or his parents? lol, nope. As a member of the guild I lead, they get a poem, a short story or some goofy / fun message in guild mail from me. Also, they and their accomplishment are on top of the guild page for a few days. About all we can do for now.

How about, "On the anniversary of our creation date, we get a present".

Each year the present would be different. One, could give our main stat a few points boost or 3 stats at random or a little to all 5?

Another year and another present asks, "Make sure you have room for 6 items before opening". A warrior, might get a full set of matching gear. Like the "Steel series". Steel armor, steel belt, etc.

Or, a few large potions, gems and a 50 % mount.....

As an alternative. having the present show up when we hit level 100, 200 etc. would be a great thing to look forward to.
